LTC1923
W U TYPICAL PERFOR A CE CHARACTERISTICS Long-Term Cooling Mode Stability Measured in Environment that Steps 20 Degrees Above Ambient Every Hour. Data Shows Resulting 0.008
°
C Peak-to-Peak Variation, Indicating Thermal Gain of 2500. 0.0025
°
C Baseline Tilt Over Plot Length Derives From Varying Ambient Temperature
1923 G13.tif
Identical Test Conditions as Above, Except in Heating Mode. TEC’s Higher Heating Mode Efficiency Results in Higher Thermal Gain. 0.002
°
C Peak-to-Peak Variation Is 4x Stability Improvement. Baseline Tilt, Just Detectable, Shows Similar 4x Improvement vs Above
